Bently Nevada 330102-00-20-05-01-05 3300 XL 8 mm Proximity Probe

Description

330102-00-20-05-01-05: 3300 XL 8 mm proximity probe, 3/8-24 UNF thread, featuring a 2.0 in fully threaded case (Option 00 unthreaded, Option 20 case length) and a compact 0.5 m total cable length (Option 05). This configuration comes standard with protective stainless steel armor on the coaxial cable and is terminated with a miniature coaxial ClickLoc connector with an integrated connector protector (Option 01), approved for hazardous area installations under CSA, ATEX, and IECEx standards (Option 05).

Unlike the unarmored 330101 series, the 330102 configuration provides robust mechanical protection for the cable via flexible stainless steel armor, preventing mechanical abrasion and cutting in demanding environments. Additionally, the Option 01 connector type includes a pre-installed fluorosilicone connector protector to guard the coaxial connection against fluid ingress, which distinguishes it from the standard Option 02 click-type connector that lacks this shield. The 0.5-meter short cable is configured for integration within short proximity loops, requiring matching 3300 XL extension cables and Proximitor sensors to form a complete 5-meter or 9-meter transducer system.

Features

• Stainless Steel Armor: Provides mechanical protection for the coaxial cable against abrasion, cutting, and environmental hazards.
• Fully Threaded Body: Option 00 specifies a 0.0 in unthreaded length, allowing maximum thread engagement across the entire 2.0 in case length (Option 20).
• Connector Protector: Option 01 includes a pre-installed fluorosilicone connector protector on the miniature coaxial ClickLoc connector to shield against liquid contamination.
• 0.5-Meter Cable Length: Option 05 offers a compact 0.5-meter (1.6 ft) total length, designed for systems with nearby terminal enclosures.
• Hazardous Area Approvals: Option 05 grants compliance with CSA, ATEX, and IECEx certifications for intrinsically safe and non-incendive environments.

Applications

• Shaft vibration and axial position measurements on fluid-film bearing machinery.
• Radial vibration, axial thrust, and thermal expansion monitoring in industrial turbomachinery.
• Keyphasor reference measurements and speed sensing.
• Heavy industrial installations including power plants, petrochemical facilities, oil and gas refineries, and rotating equipment.

Installation Guidelines

• Avoid over-tightening the probe case; the maximum length of thread engagement for 3/8-24 UNF-2A threads is 0.563 inches (14.3 mm).
• Ensure ClickLoc connectors are kept clean and free from contamination. Slide the pre-installed connector protector over the coaxial connection to prevent fluid ingress.
• Maintain a minimum bend radius of 25 mm (1.0 inch) for the armored coaxial cable to avoid crimping.
• Set the initial probe gap to approximately -9 Vdc (typically 1.27 mm or 50 mils) when using an AISI 4140 steel target for radial vibration measurements.

Compliance and Certifications

• CSA/ATEX/IECEx: Certified for intrinsically safe and non-incendive environments (under Option 05).
• CE: Fully compliant with European electromagnetic compatibility and electrical safety regulations.
